Abstract

A light-weight, high-strength compressor component having at least one fluid delivery feature that is formed via additive manufacturing is provided. The component may have at least one interior region comprising a lattice structure that comprises a plurality of repeating cells. A solid surface is disposed over the lattice structure. The interior region comprising the lattice structure has at least one fluid delivery feature for permitting fluid flow through the body portion of the light-weight, high-strength compressor component. The fluid delivery feature may be a flow channel, a fluid delivery port, a porous fluid delivery feature, or the like that serves to transfer fluids through the component, such as refrigerant and/or lubricant oils. Methods of making such compressor components via additive manufacturing processes are also provided.

First claim

What is claimed is:

2. The light-weight high-strength compressor component of claim 1 , wherein the at least one fluid delivery feature is an open channel formed within the compressor component body portion for fluid communication within the compressor component, wherein the open channel is separated from the at least one sealed interior region that comprises the lattice structure by a solid internal wall.

3. The light-weight high-strength compressor component of claim 2 , wherein the open channel permits flow of lubricant oil or refrigerant.

4. The light-weight high-strength compressor component of claim 1 , wherein the lattice structure comprises a metallic lattice structure and the solid surface comprises a metallic surface.

5. The light-weight high-strength compressor component of claim 1 , wherein at least one fluid delivery feature comprises a fluid delivery port connected to at least one channel that provides fluid communication within the compressor component.

6. The light-weight high-strength compressor component of claim 1 , wherein at least one fluid delivery feature comprises a compressor component fluid delivery port selected from the group consisting of: bleed holes, vapor injection ports, liquid injection ports, valve placement ports, modulation ports, pressure feed ports, variable volume ratio ports, compressor component discharge ports, compressor component suction ports, and combinations thereof.

7. The light-weight high-strength compressor component of claim 1 , wherein at least one region of the at least one fluid delivery feature comprises a porous material.

8. The light-weight high-strength compressor component of claim 7 , wherein the porous material has a first region with a first average pore size and a second region with a second average pore size, wherein the second average pore size is smaller than the first average pore size.

9.
